Objectives: The primary aim was to determine the prevalence of gastrointestinal diseases in patients with chronic rhinosinusitis (CRS), utilizing the National Health Insurance Research Database (NHIRD) in Taiwan. Several studies have supported the existence of distinct immune patterns between the Asian and Western populations in CRS patients. Through the population-based case–control study, we could compare the differences between various regions and provide further treatment strategies for subsequent studies in Asian CRS patients. The secondary aim was to assess whether different types of CRS influence the correlation with specific GI diseases. Understanding how different phenotypes or endotypes of CRS may relate to distinct GI disease patterns could provide valuable insights into the underlying mechanisms and potential shared pathways between these conditions. Methods: We use the NHIRD in Taiwan. Newly diagnosed patients with CRS were selected between January 1, 2001 and December 31, 2017 as the case group, and the controls were defined as individuals without a history of CRS. Patients with CRS were divided into two groups: with nasal polyps and without nasal polyps. We also separated GI tract diseases into four groups based on their different pathophysiologies. Results: This study included 356,245 participants (CRS: 71,249 and control: 284,996). The results showed that CRS was significantly associated with some specific GI tract diseases, including acute/chronic hepatitis B, gastroesophageal reflux disease (GERD) with/without esophagitis, achalasia of cardia, peptic/gastrojejunal ulcer, Crohn’s disease, and ulcerative colitis. In addition, when CRS was subcategorized into chronic rhinosinusitis with nasal polyps (CRSwNP) and chronic rhinosinusitis without nasal polyps (CRSsNP), GERD with esophagitis and peptic ulcer were significantly associated with CRSsNP. Conclusions: A significant association between CRS and premorbid GI tract diseases has been identified. Remarkably, GERD with esophagitis and peptic ulcer were significantly associated with CRSsNP. The underlying mechanisms require further investigation and may lead to new treatments for CRS. Researchers can further investigate the mechanisms by referring to our classification method to determine the implications for diagnosis and treatment.
